To @ZZ whom, it may concern.'

Be it known that I, WILLIAM C. ELLIs, of Marshalltown,county ofMarshalhand State of Iowa, have invented a new and useful Improvenientin Bath-Boilers, of which t-he following` is a co nplete specification.

My invention consists in an improved automatic cut-off andheat-regulator combined in such a manner with a boiler that they may beoperated together. My cut off devices areV so connected with the heateras to prevent explosions from steam, and so constructed and placed thatthey will not freeze. By my peculiar arrangement of the aforesaiddevices the operator is enabled to control the circulation of waterthrough the heater.

The mechanism ofmy invention is illustrated in the accompanyingdrawings, in which Figure l is a front view of the boiler, part beingbroken away, and heater, showing their connection. Fig. 2 is a back viewof a vertical section ofmy cut-off devices,illustrating their connectionand the course of circulation.

A is a stand-boiler.

B is a water back or reservoir resting on a stove or furnace.

C is a pipe connected with the water-main or other source of supplywhich empties into the boiler A.

E is a pipe which conveys water from the boiler to the water-back orheater.

D is a pipe which conveys the water from the heater into the boiler.

a is the shell of the first cutotf,and contains a hollow plug, b.Integral with I) is a pipe, h, so perforated as to afford freecommunication between the boiler and the supply-pipe C.

c is the shell of the second cutoff, and contains a plug, d, which isjoined to h.

e is the shell of the third cutoff, and contains a plug, f, which isjoined to d. The opening or closing of the connection between theinterior of the boiler and the pipes C, D, and E depends upon therotation of the plugs b, d, and f. In the shell e, inline with the pipeE, is an oblique channel, P, downward to the plugf, on the side towardthe heater. The

lower part of the plugf is hollow,and at right angles to the orificecorresponding to the pipe E is a lower orifice corresponding to thechannel p.

m is a shaft connected with the plug b,which projects out oftheboiler,and which is integral 'with a crank. The crank is joined by tworods, a ando, to a damper, F, in the stove or furnace in such a mannerthat when the damper allows the heat to increase the plugs allow thewater to circulate, and when the damper diminishes or cuts off theheat-supply the circulation of water through the boiler and water-backdiminishes or ceases. Then the heat and water-supply are cut off, thelower orice in the plugj' is opposite the channelp, and water flows'from the reservoir B through the pipe E and plugf from the boiler.

In the operation of my invention the crank m is rotated so as to adjustthe damper F to increase the heat, and it consequently adjusts the plugsZ), d, and f, respectively, to the pipes C, D, and E. Vater flowsthrough b and h into the boiler. Being cold,it sinks to thel level of E,and passes through f into the reservoir B. Here it is heated and flowsback through D and d into the boiler, in which it rises to the top, andwhence it may be drawn as desired. If now the crank m be rotated so asto shut off the heat, the plug b shuts ofi` the water-supply, while thereservoir is drained through the plug f. The cut-off devices, being inthe: interior of the boiler, will not freeze, and the peculiarconstruction of the plugf obviates danger from steam.

The entire device is easily'operated by the crank m, and may be readilyattached to any heater.

I claim as my inventionl. The combination of a standboiler with asupply-pipe extending into the boiler and provided with a valve withinthe boiler, a drain-pipe extending into the boiler and provided with avalve within the boiler, a connection between the two valves rigidlyuniting them, and an extension from the stem of one of said valvespassing outside the boiler, substantially as and for thc purposes shownand described.

2. The combination ofa stand-boiler, a supply-pipe extending into theboiler and provided with a valve within the boiler, a drainpipeextending into the boiler and having a valve within the boiler, withpipes communicating with the water-back, one of which extendsinto theboiler and is provided with a valve within the boiler, a connectionrigidly IOO uniting all of the valves, and an extension'] provided witha valve having a hollow-plug so from one of the valve-stems passingoutside of the boiler, substantially as described.

3. The combination .of a stand-boiler, a supply-pipe extending into theboiler and provided with a valve having a hollow plug connected with thepipe within the boiler, pipes communicating with the water-back, theupper one ci' which extends into the boiler, and is provided withavalveWithin the boiler, a pipe connected to they hollow plug of thesupply-pipe valve and to the stem of the Waterback valve, rigidlyuniting the same, said pipe being provided with perforations near to itslower end, and an extension from the other vvalve-stem passing outsideof the boiler, substantially as described.

4. The combination of a stand-boiler, a supply-pipe extending into theboiler and connection with the pipe within the boiler,

pipes communicating with the water-back, y

the upper one of which extends into the boiler, and is provided with avalve Within the boiler, a pipe connected to the hollow plug of thesupply-pipe valve and to the stern of the Waterback valve, rigidlyuniting the same, said pipe being provided with perforat'ions near thelower end, and an extension from the other valve-stem passing outsidethe boiler, and the damper of a range connected With a crank attached tothe plug of the supply-pipe outside the stand-boiler by two links,substantially. as described.
